PORTABLE ROOF.

SPECIFICATION forming part of Letters Patent NO. 473,128, dated April19, 1892.

Application filed July 8, 1891. serial No. 398,848. (No model.)

To all whom it may concern.-

Be it known that I, EDMUND RANKIN, J r., a citizen of the United States,residing at Lincoln, in the county of Logan and State of Illinois, haveinvented certain new and useful Improvements in Portable Roofs andSiding, of which the following is a specification, reference being hadtherein to the accompanying drawings, in which- Figure 1 represents aperspective view of my improved portable shed erected, a few of theupper boards being removed; Fig. 2, a detail perspective viewshowing-more clearly the improved hooks; Figs. 3 and 4,detail sideelevations of portions of the supports, showing the hooks in position,the hooks in the latter view being slightly modified in construction;Figs. 5 and 6, detail perspective views of the two forms of hooks shown,respectively, in Figs. 2 and 4.

This invention has relation to that class of portable sheds and roofscovered by Letters Patent No. 451.572, granted to me on the 5th day ofMay,1891; and it has for its objects to simplify and improve theconstruction shown in said patent, whereby the devices shall be renderedmore substantiahcheaper, and easier of erection and removal, as willmore fully hereinafter appear.

This invention has particular reference to the hooks employed to holdthe boards or siding on the rafters.

In the drawings, a designates the inclined supports or rafters pivotedtogether in pairs in a suitable manner at their upper ends and connectedtogether by the usual adjustable stays 1), whereby their pitch may bevaried, as fully described in my former patent. The rafters or supportscarry the hooks c, that support the boards (1. The preferred form ofhook is that shown in Fig. 5, wherein it is shown constructed of asingle piece of wire bent into shape, forming a loop c',which embracesthe rafter, the two ends of the wire being bent downwardly and formedinto U- shaped books 0 for the reception of the lower edges of theboards. The loops 0' are preferably formed rectangular in shape, so asto embrace the rectangular rafters, and their outer ends when in placeon the rafters project outwardly from the outer edges of the rafters andextend down'over the upper edges of the boards below, thereby serving tohold the lower boards in place and also to form sockets or hooks for thereception of the lower edges of the upper boards. These hooks mayloosely embrace the rafters, so as to readily slide up and downtl1ereon, whereby theyniay be adjusted to accommodate boards ofdifferent widths, or the loops may be stapled to the inner edges of therafters, as at c' in Fig. 3. In either case the hooks will have a freevertical swinging or pivotal motion on the rafters, so as to enable themto be readily ad justed to position.

Instead of carrying both ends of the wire of the loops out and formingthem into two hooks c, as in Fig. 5, one part of the wire may terminateat the side of the rafter and only one hook c" be employed, as shown inFigs. 4 and 6.

The purposes of this invention, its variety of uses, and the manner oferecting and taking it apart are fully set forth in my former patent,and therefore need not be set out here.

Having fully described my invention, what I claim is 1. Thecombination,with supports a, of a series of hooks 0, carried by each ofthe supports, said hooks each consisting of a wire bent into a loop owhich embraces the support, the ends of the wire being carried outwardlyon opposite sides of the support and formed, one or both, into dependinghooks 0" beyond the outer face of the same, and the boards (1, eachhaving their lower edges resting in the series of hooks 0" next belowand their upper edges under the series of hooks next above,substantially as and for the purpose described.

2. The combination of a support, the pivoted hooks embracing the sameand projecting outwardly therefrom and formed into depending hooks c",said hooks 0 being beyond the outer face of the support, and inclinedboards cl, having their lower edges resting in said hooks c" and theirupper edges resting under the series of hooks above, substantially asand for the purpose-described.

In testimony whereof I affix my signature in presence of two witnesses.

EDMUND RANKIN, JR.
